This is the Dr. Bones Color Lab Playset from Hot Wheels Color Shifters. Perform your own color changing by taking your Colour Shifters Cars through this mad scientist laboratory. Should he decide to trap your car in his jaw cage, don't worry! Rescue it using the giant skeleton hand, one swift blow and his skull will explode! Includes 3 activation modes for dynamic color change plus a launch and loop with water splash. It changes color with warm, cold and hot water. The playset comes with one Hot Wheels Color Shifter Creature Car. There are dozens of other Color Shifters Cars available from Hot Wheels to add to your collection. But Color Changers do not work in this track, only in the spinning platform. I used Lightning McQueen from Disney Pixar Cars to try it out. Using the spray pump it allows you to instantly change your car's paint job with just a squirt of water. Designed for children ages four and older, Drench it with the spray or dip it in one of the dunk tanks, and watch it change colors before your eyes. Special appearances by Peppa Pig and "Toy Story color splash buddies".
